Canton
is shipping its newly redesigned Ergo loudspeakers with new drivers and
crossover networks incorporating technological advancements developed
for the recently introduced Vento line. The Ergo line includes a trio
of three-way floorstanders, three compact two-way models, a 2-1/2 way
center channel, and an improved 350 Watt powered subwoofer.

The full range models in the Ergo line employ the company's latest
ADT-25 aluminum-manganese dome tweeter. The most significant change to
the driver is a flared transmission front plate which delivers improved
high frequency dispersion and off-axis linearity, and reportedly
increases driver efficiency by 2- to 3- dB overall. The revised ADT-25
employs Canton's one-piece aluminum-manganese dome and voice coil
former for high frequency performance and heat dissipation while the
surround design has also been tweaked to reduce distortion and make it
less susceptible to break-up modes. All these changes extend the
tweeter's effective operating range up to 40 kHz while limiting
distortion.

The bass and midrange drivers in the Ergo line feature stiff and
lightweight black anodized aluminum cones for optimum response. The
drivers were developed for the Vento series for a 60 to 100 percent
increase in excursion capabilities, and a 6- to -9 dB increase in deep
bass output.

The new line also incorporates the most dramatic change in cabinet
design the line has seen in over two decades. The front baffle
incorporates a curve across the face of the speaker that is actually
supposed to reduce deleterious edge effects. Additionally, the
floorstanding models have bottom plates that improve isolation from the
floor. The increased structural support of both the baffle and the
bottom plate also serves to further reduce cabinet resonance.

The three floorstanding models in the Ergo line use Canton's exclusive
Displacement Control (DC) technology to prevent signals below the
audible frequency range from interfering with the bass driver. In
conventional speakers, these signals can generate high levels of
unwanted harmonic distortion in the audible lower bass range, causing a
muffled tonal quality. DC technology allows the speakers to provide
clear, linear bass reproduction at much lower frequencies than could
otherwise be attained.
